Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed September 5, 1905. Serial No. 276,971.

To all whom it may concern:

Be it known that I, WALTER JoRGENsEN, a subject of the Emperor of Russia, residing at Stockholm, in the Kingdom of Sweden, have invented a new and useful Improvement in Regulating-Turbines for Separators, of which the following is a specification, due reference being had to the drawings which accompany and form part of this application, similar letters denoting similar parts.

I/Vith separators driven by turbines if the supply of the milk ceased and if the steamsupply was not simultaneously shut off there would arise the inconvenience that the separator, which would consequently be running empty, could acquire such a speed as would impose a dangerous strain on the strength of the rotating parts.

My present invention has for its object to avoid said risk; and it is based upon the fact that the milk-supply can of the separator or the regulating-cover must be emptybefore said phenomenon can occur.

My invention, speakin -generally, consists in providing a control ing valve for the steam admitted to drive the turbine and controlling that valve by the amount of milk in the supply-can or regulating-cover 'i. e.,-

controlling the position of the valve by the quantity of milk in the reservoir. I also provide an arrangement so that at no time is the supply of steam entirely out off, but even if the valve-is closed an opening is left of such size that steam will pass sufficient to main tain a constant speed with the empty bowl. This latter I can do either by preventing the valve from entirely closing or providing an opening in the valve which registers with the steam-passage when the valve is closed. Speaking specifically, I arrange a float or the like in the supply-can or in a receptacle, the regulating-cover containing the milk to be treated in the separator or in a separate receptacle communicating therewith, and is connected, by means of a rod, a cord, or the like, with a valve arranged into the steamsupply pipe. In this way the valve will be put into 0 eration when the float sinks, and

- i when the oat has reached the bottom of the can the valve will be almost quite shut off. In another constructionalform I suspend the whole receptacle of the regulating-cover on a balance. When the receptacle is empty, the balance, which is connected with the valve, assumes such a position that the valve will be 5 5 almost entirely shut ofi.

My invention further has also, as stated, for its object an improvement by which the steam-supply will not fully shut off, but so great a quantity of steam will be supplied 6o as corresponds to the running of the separator empty, in order that the separator may not, if the supply-can or the regulating-cover has been emptied, stop, but maintain its speed.

The invention is shown on the annexed drawings, wherein Figure 1 is a side elevation, partly in section, of a structural form of my invention. Fig. 2 is a plan view of same. Fig.- 3 is a side elevation of another structural form, partly in section and Fig. 4is a plan view of same. Fig. 5 is a sectional view of a modified form of valve.

Taking up first Figs. 1 and 2, a is the regue 7 5 lating-cover of a liquid-separator, which by means of a pipe I) communicates with a receptacle c for the liquid to be separated. In this receptacle, as shown, or, of course, in the' regulating-cover, as the case may be, if the receptacle 0 is omitted a float d is arranged, whichby means of a rod e is connected with a valve of a suitable type. On the drawings I have shown a valve, the cock f of which is turnable into the box 9. The cock f is provided with a projecting lever h, and with this lever h the rod 6 is connected. The cock f of this valve is provided. with a hole '6. When'the valve is operated by the float d by means of the rod 6, so as to'take the position 0 shown in dotted lines in Figs. 1 and 3, which will occur when the supply-can or the regulating-cover is empty and the float rests on the bottom of the receptacle 0, the valve will not be quite shut off, but a small quantity of 5 steam can pass through the hole i, so that the separator may maintain its speed, though it is now running empty. As soon as the supply-can or the regulating-cover is refilled the float rises and then the cock f will be turned, :00 so that the full steam-supply is admitted, I It is obvious that insteadof the hole i other ap liances may be used with-the same res t i. 8., the partial supply of steam, ,For;

instance, the hole i may be omitted and the cock f by means of a clutch be prevented from entirely shutting off the supply of the steam.

In the modified form shown in Figs. 3 and 4 the gravity of the milk in the supply-can or in the regulating-cover is used for the operation of the valve. The receptacle a of the regulating-cover in this case is suspended on the one end of a balance is, the other end of which is connected with the rod Z. On said rod a counterweight m is arranged, the gravity of wlhichcorresponds to that of the receptacle a, when filled. The rod Z is connected with a valve of any convenient type, as a turning-valve of the shape shown in Figs. 1 and2. As soon as the level of the milk in the reoe tacle a sinks, whereby also the gravity of t e receptacle (1 decreases, the weight m will sink, and the valve-cocky is operated to shutoff the steam-supply more or less. As before, when the receptacle is empty and the weight m hassunkto its lowest point, the valve is not entirely shut off, but permits, through passage i, a suflicient quantity of steam to pass as is required for the separator to run empty.

In Fig. 5 I have shown arotary valve or for controlling the admission of the steam, having an orifice 0 through it, which when the valve is turned to closed position registers with the steam inlet and allows sufficient steam to pass to the inlet to keep the empty bowl at constant speed. This valve may be connected to either the arrangement of Figs. 1 and 2-or Figs. 3 and 4.
